I don&#39;t know what an i&lt;u&gt;&lt;b&gt;m&lt;/b&gt;&lt;/u&gt;put variable is.  But presuming you meant &lt;i&gt;input&lt;/i&gt;, the input variable is the &lt;u&gt;independent&lt;/u&gt; variable.


The output variable is the &lt;u&gt;dependent&lt;/u&gt; variable.  Remember, the output &lt;i&gt;depends&lt;/i&gt; upon the input.
